Elections for the Chamber of Representatives of the Croatian Parliament were held on 3 January 2000. These were the first elections to be held after the expiration of a full term of the previous Chamber.
The ruling Croatian Democratic Union entered the elections weakened by the Zagreb Crisis, street protests and the series of corruption scandals that came to light in the previous parliamentary term. However, the most important factor was the deteriorating health of the party leader and Croatian president Franjo Tuđman, which sparked a succession struggle between various factions within the party.
Like before all previous elections since the breakup of Yugoslavia, the electoral laws were altered in an attempt to improve the chances for the ruling party; this included a new voting system and redistricting. The First Past the Post constituencies introduced in the previous election were completely abandoned and Proportional Representation was implemented (with the exception of single representative ethnic minority seats). Croatia was divided into ten electoral districts, all drawn in order to maximise the support for HDZ. Each district had to elect 14 members, with candidates' lists having to win more than 5% of the votes in order to be represented in the Sabor.
Due to Tuđman's illness and death, the actual date of elections had been repeatedly postponed for constitutional reasons. There were speculations about elections being held during the Christmas holidays in order to have as many Croatian expatriates (traditional HDZ supporters) in the country, but the date of 3 January was chosen as the most suitable. As the day of the elections approached, its outcome became more certain. The campaign was brief and relatively uneventful with the HDZ being visibly weakened and demoralised by the death of its long-term leader. On the actual day of elections the turnout - the biggest since 1990 - indicated the Croatian people's desire to have their government changed.
